It's a wonderful change to read wise and usefully tips and content really feeling part of the MB community. After many years of company cars, I have finally bought a MB e300TD, (family growing!!)and with words of encouragement and advice, dusted off the old toolbox and soon rectified my 'air in diesel' problem. Changed the fuel lines, which helped a bit, but the icing on the cake, a simple £1.33 'O' ring on the shut-off valve. I'm sure I have saved hundreds in labour costs, as I didn't even have to remove the intake manifold. Here's to many more years of excellent MB motoring and new friends.
